DISPERSIBLE MOIST WIPE AND METHOD OF MAKING
A dispersible moist wipe includes regenerated cellulose fibers in an amount equal to or less than 20 percent by weight and natural cellulose fibers in an amount equal to or greater than 80 percent by weight. At least 50 percent of the natural cellulose fibers are fibrillated. The regenerated cellulose fibers and the natural cellulose fibers are hydroentangled such that the web has a wet CD tensile strength of at least 200 grams per inch. A method of making a dispersible nonwoven sheet includes dispersing natural cellulose fibers and regenerated cellulose fibers in a liquid medium to form a liquid suspension and depositing the liquid suspension over a forming surface to form a nonwoven web. The natural cellulose fibers and regenerated cellulose fibers of the web are hydroentangled using a plurality of hydroentangling jets.
Nonwoven fabric and method for manufacturing same
An extensible nonwoven fabric, and method for its manufacture, on which the source, medicinal component, pattern and/or other pieces of information are recognizable at the beginning of and during fabric use. It is made mainly of highly crimped fibers, with a compressed region where no fibers are melted and bonded together, with a tensile strength of 25 N/5-cm-width or more in both the machine direction and the cross direction. It may be manufactured by causing a water jet having a pressure of 5 MPa or more to act onto a web made mainly of a latent crimpable fiber, forming an entangled fiber web, causing heat to act on it, crimping the fiber converting it to a highly crimped fiber while contracting the web's area by 30% or more forming a contracted fiber web, and embossing it such that the fibers are not melted and bonded together.

Nonwoven fabric for increasing the availability of quaternary ammonium in solution
Wipes for preventing quaternary ammonium (quat) depletion suitable for commercial applications (e.g., industrial and consumer disinfectant wipes) are provided. The wipe includes at least one nonwoven layer, at least one pulp layer, and a cationic additive. The at least one nonwoven layer and the at least one pulp layer may be hydroentangled to form a hydroentangled nonwoven fabric having a first surface and a second surface. Additionally, the cationic additive may be disposed on at least one of the first surface or the second surface.

PLANT AND METHOD FOR CONNECTING A WEB OF FIBROUS MATERIAL TO A NONWOVEN OR CONSOLIDATING IT THEREWITH
A plant and a method for connecting a web of fibrous material to a nonwoven or consolidating it therewith includes a first circulating belt on which the web of fibrous material is laid, a device for introducing a nonwoven into the plant, and a further successive circulating belt on which the nonwoven is to be connected to or consolidated with the web of fibrous material. The web of fibrous material from the first circulating belt is first laid on the nonwoven and subsequently the fibrous material is transferred onto the successive belt together with the nonwoven for connection or consolidation by use of water jets.

NONWOVEN FABRICS AND METHODS OF MAKING AND USING SAME
Substantially compostable nonwoven fabrics comprising staple fibers made from natural cellulosic fibers optionally mixed with other natural, man-made or synthetic fibers are described. Also described are methods of preparing such nonwoven fabrics that can include the steps of at least one of needle punching and/or hydroentangling and optionally resin bonding and/or thermal bonding. The compostable, or substantially compostable nonwoven fabrics disclosed herein provide improved durability over conventional nonwoven fabrics.
Composite material and method for making same
A composite material includes a nonwoven layer having a plurality of fibers and a polymer film layer with a plurality of extended cells. Each of the extended cells are contemplated to include continuous sidewalls extending away from the nonwoven layer. At least one of the fibers extends into one or more of the extended cells.
Fabric having tobacco entangled with structural fibers
A smokeless tobacco product includes smokeless tobacco and structural fibers. The structural fibers forming a network in which the smokeless tobacco is entangled. The structural fibers have a composition different from the smokeless tobacco. The tobacco-entangled fabric can have an overall oven volatiles content of at least 10 weight percent. In some embodiments, the structural fibers form a nonwoven network. In some embodiments, fibrous structures of the smokeless tobacco are entangled with the structural fibers.
